如何获取GridView中的checkbox的id

您好，

在我的应用我使用GridView控件更新面板。在该GridView中，我使用1 CheckBox控件和3下拉。复选框我有CheckedChanged事件，我有三个下拉选定指数的变化事件。当复选框被选中的事件被解雇和页面令人耳目一新。而同样的情况下拉控制。我的问题是，我想选定指数的变动情况和检查更改事件应该发生而无需刷新页面。我曾试图给异步后回触发控制，但没有奏效。任何人都可以请帮我解决这个问题。这里是代码:

  <table align="center" class="css_MainTable">

                                  <tr>

        <td align="center" colspan="2">

            <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">

                <ContentTemplate>

                    <asp:GridView ID="gvTenderTeam" runat="server" AutoGenerateColumns="False" 

                        CssClass="css_gridview" GridLines="Vertical"

                        onrowdeleting="gvTenderTeam_RowDeleting" onrowediting="gvTenderTeam_RowEditing" 

                        onselectedindexchanged="gvTenderTeam_SelectedIndexChanged" >
